Does the Kindle app require a menu and/or back button? That's my biggest concern with buying one. I'm certain that this i sa first step in liberating the NC in all it's glory, but the lack of the physical buttons makes me wonder how far this can actually go. One thing I've actually seen suggested is using the volume buttons for back and menu, which seems like a great idea--especially since volume control can be accessed from onscreen settings.

Staying with imperial measurements has only served to handicap American industry and economy. Attempts to get Americans using the Celsius scale or putting up speed limits in kilometers per hour have been squashed dead. Not only that, but some Americans actually see metrication efforts as an assault on "our way" of measuring.

I personally deal with European scientists on a daily basis, and find our lack of common measurement to be extremely frustrating. Are we so entrenched with imperial units that we cannot get our fellow citizens to simply learn something new? What are those of us who wish to finally see America catch up to the rest of the world supposed to do? Are there any organizations that we may back, or any pro-metric legislators who we can support?"
